Asbestos in My Building

Information presented in this publication is intended to provide a general understanding of the statutory and regulatory requirements governing managing asbestos. This information is not intended to replace, limit or expand upon the complete statutory and regulatory requirements found in the Illinois Environmental Protection Act and Title 35 of the Illinois Administrative Code.

This fact sheet does not apply to privately owned homes and apartments with four or less units.

Asbestos is a naturally occurring mineral found in certain rocks. This mineral separates into strong, thin fibers that are invisible to the naked eye. Asbestos was commonly used in building materials before the mid-1970s and occasionally until the late 1980s because it is strong, fire- and corrosion-resistant, and a good insulator. Common uses of asbestos include the following:

• As a building material additive to enhance strength (for example, asbestos was added to concrete, asphalt, and vinyl materials in roof shingles, pipes, siding, wall board, floor tiles, joint compounds and adhesives)
• As a fireproofing material applied on steel beams and columns during construction of multistory buildings
• As a thermal insulation and as a means of controlling condensation
• As an ingredient in acoustical plaster
• As a component of a mixture sprayed on ceilings and walls to produce a soft, textured appearance

If the materials discussed above contain more than one percent asbestos as determined using polarized light microscopy (PLM), they are considered asbestos-containing materials (ACM). ACM can be friable or nonfriable. When dry, friable ACM can be crumbled or reduced to a powder by hand pressure and presents greater health risks to human health than nonfriable ACM. When dry, nonfriable ACM cannot be crumbled or reduced to a powder by hand pressure.

If ACM is in good condition and left in place, it should not present health risks. However, if the ACM has been damaged or is crumbling, or if a building is to be demolished, renovated, or remodeled, care must be taken to prevent the release of asbestos fibers into the air. Inhalation of microscopic asbestos fibers from friable ACM can cause health risks. Once inhaled, asbestos fibers can become lodged in tissue for a long time and can cause cancer.

Asbestos can also cause asbestos-related diseases or problems such as asbestosis, a progressive, disabling and potentially fatal disease; mesotheliona, a rare cancer of the mesothelium, the thin tissue layer that lines body cavities and surrounds internal organs; and pleural plaques, scar tissue in the chest cavity. The number of fibers a person must inhale to develop asbestos-related disease is not known. At very low exposure levels (such as being in the same room as a cracked tile containing asbestos), the risks can be negligible. However, during demolition, renovation and removal activities, risks from exposure greatly increase. Also, smoking greatly increases the risk of asbestos-related lung cancer. Almost all known cases of asbestos-related lung cancer occurred among people who smoked and were exposed to asbestos.

Because asbestos presents a significant risk to human health when released to air, asbestos is considered a hazardous air pollutant regulated under the National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations.

NESHAP regulations are Federal regulations under the Clean Air Act (CAA) that apply to the facility owners and contractors who perform work in public and commercial buildings. Asbestos NESHAP regulations address common small business activities such as milling, manufacturing and fabricating operations, demolition and renovation activities, waste disposal issues, active and inactive waste disposal sites, and asbestos conversion processes. A privately owned home or an apartment with four or less units is exempt from the regulations unless the building has either had previous use or future planned use as a commercial or public facility. For privately owned homes and apartments with four or less units, please refer to the fact sheet titled "How Do I Manage Asbestos In My House Or Apartment Building?"

The term "facility" as used in NESHAP regulations refers to a residential structure or any building that has been or will be used as a commercial property. The only exemptions are privately owned homes or residential structures having four or less dwelling units.

Category II nonfriable ACM consists of any material except for Category I nonfriable ACM that contains more than one percent asbestos as determined using PLM and that when dry, cannot be crumbled, pulverized, or reduced to powder by hand pressure.

If an inspector has determined that regulated ACM removal is necessary, a notice of the removal must be delivered or postmarked to the Illinois Environmental Protection Agency (Illinois EPA) at least 10 working days prior to the commencement of demolition or renovation if the amount of regulated ACM to be removed exceeds 160 square feet, 260 linear feet, or 1 cubic meter.

Although you will hire a licensed contractor to conduct regulated ACM removal work, you should be aware of the requirements below for contractors during removal activities.

• A NESHAP-trained person must be present.
• The area from which the asbestos will be removed should be sealed off and any forced-air heating systems should be shut off.
• Workers should wear a respirator fitted with cartridges that filter out asbestos fibers.
• The asbestos should not be broken into small pieces because this can increase the amount of airborne asbestos fibers.
• The asbestos should be kept wet during the entire removal process.
• The asbestos waste should be containerized and labeled for disposal at an approved landfill.
• The area from which the asbestos was removed should be cleaned thoroughly with a wet mop, rags or sponges.
• Asbestos removal workers should decontaminate themselves.

Only a licensed contractor should remove regulated ACM. Licensed asbestos contractors can be found in the telephone book yellow pages or by calling the Illinois Department of Public Health at (217) 782-3517.

In addition to NESHAP requirements, other regulatory standards apply to asbestos. The first two items listed below apply to regulated ACM removal contractors, and the remaining items apply to the facility owner.

1. The Asbestos School Hazard Reauthorization Act extends the training requirements specified in the Asbestos Hazard Emergency Response Act, which regulates asbestos removal in schools, to public and commercial buildings.
2. The Commercial and Public Buildings Asbestos Abatement Act, which is a state regulation administered by the Illinois Department of Public Health, requires that asbestos project designers, inspectors, workers, supervisors, and contractors to be licensed prior to performing their respective duties in public and commercial buildings for each project where the amount of friable ACM involved exceeds 3 square or linear feet.
3. The Occupational Health and Safety Administration (OSHA) regulates the abatement of asbestos. Employers are required to (1) identify or presume the presence of asbestos in the workplace; (2) communicate that information to their employees; (3) meet training, medical surveillance and exposure documentation requirements for employees working with and around ACM; and (4) follow certain practices and procedures during disturbance of ACM.
4. Local governmental agencies may also have asbestos-related regulations. For example, the City of Chicago and Cook County have ordinances that require the filing of notices and fee assessments. Contact local governmental entities in your area prior to conducting any renovation or demolition activities.
